A 54-year-old postmenopausal female presented by abnormal vaginal bleeding. On TVS examination, there was a large echogenic lesion in the endometrial cavity measuring about 12 mm in diameter with cystic changes inside. a, b Sagittal and axial T2 WIs show endometrial thickening. The polyp appears of slightly low signal intensity compared with normal endometrium (red lines). There is a low signal intensity central fibrous core (blue arrows), and small high signal intensity intratumoral cyst (yellow arrows). c Axial DWI with b value of 1000 s/mm2 shows high signal intensity of the thickened endometrium. The polyp appears of intermediate SI lower than that of the endometrium (red arrow). d Axial DW-ADC map image shows thickened endometrium with intermediate signal intensity. Mean DW-ADC value = 1.511 × 10−3 mm2/s. e, f Sagittal, and axial DTI map images demonstrate endometrial polyp mean DT-FA value = 0.518, and mean DT-MD value = 1.477 × 10−3 mm2/s. Diagnosis: pathologically proven endometrial polyp
